SPECIFICATION forming part of Letters Patent No. 327,163, datedSeptember 29, 1885.

Application filed December 11, 1882.

To aZZ whom it may concern;

Be it known that I, W'ILLIAM HARVEY, of Augusta, in the county ofKennebec and State of Maine, have invented a new and useful Improvementin Scythes, which improvement is fully set forth in the followingspecification and accompanying drawings, in which- Figures 1, 2, 3, and4. are sectional views of the common form of scythes and themodifications I propose.

My invention relates, first, to the construction of scythes, making themlight but capable of resisting a great strain, which I accomplish byhollowing the back on one or both sides and corrugating the web.

In the drawings, Fig. 1 is a sectional view of a common scythe toillustrate the difference between the present construction and the onewhich I propose. Figs. 2, 3, and 4 are sectional views of scythcsconstructed according to my invention.

Z), Z), and b are the backs, and w w 'w the webs.

In Fig. 2 the back is hollowed on the inside at a; in Fig. 3 it ishollowed on the outside at a, and in Fig. 4 on both sides, a" and a.This hollowing of the backs, while it makes them considerablylighter,does not materially (N0 model.)

weaken them, because the greater part of the strain is upon the outeredges, which are left as in the common scythe.

The web is corrugated next the back, as indicated. This corrugation hasthe efiect to greatly strengthen the scythe and make it capable ofresisting a much greater lateral strain than when constructed in thecommon form. It also enables the maker to use a thinner web. The resultis that with a less amount of material a lighter and stronger scythe isobtained.

\Vhat I claim as myinvention, and desire to secure by Letters Patent ofthe United States, 1s

1. A scythe having the back thereof concave on one or both sides, asindicated in Figs. 2, 3, and 4, as and for the purposes set forth.

2. A scythe having the back thereof concave on one or both sides and theweb or blade corrugated from the junction of the web and back to a linenear the cutting-edge of the web, and substantially parallel therewith.

WILLIAM HARVEY.
